Dependence effects in unique signal transmission
''Unique Signals'' are communicated from a source to a ''strong link'' safety device in a weapon by means of one or more digital communication channels. The probability that the expected unique signal pattern could be generated accidentally (e.g., due to an abnormal environment) would be an important measure. A probabilistic assessment of this likelihood is deceptive, because it depends on characteristics of the other traffic on the communication channel. One such characteristic that is frequently neglected in analysis is dependence. This report gives a mathematical model for dependence; cites some of the ways in which dependence can increase the likelihood of inadvertent unique signal pattern generation; and suggests that communicating each unique signal ''event'' at the highest level of protocol in the communication system minimizes dependence effects. 3 refs., 4 figs.
